The Research And Design Of Virtual Computer Communication Experimental System

Computer communication technology is an important course for the communications and electronics professionals. As an important part in the teaching process, experiment is an indispensable tache and hold an important position in teaching, But in the traditional teaching of communication experiment, there are lots of problems in many higher vocational schools especially in private schools, such as lacking capital,device insufficiency,equipment obsolescence and so on.Virtual experiment system is an important application of virtual reality in the field of education, It uses computer technoloy to establish a comprehensive, multi-level,multi-mode teaching and learning environment, so that the students' practive skills and operational skills can been fully improved.In this paper, I introduce the virtual experimental techniques and analyse the situation of computer communication experiment,then propose a new experimental mode—computer communication virtual experiment system, Experimenter can be divorced from the specific experimental environment, to carry out experimental operation in PC,achieving the thinking of "software-as-intrument". The motive of developing this system is to solve the problems that faced in Xi'an Eurasia University,such as the lack of equipment, make up the deficiencies in the teaching experiment. The thesis research work includes:1. Introduce techniques and current status of virtual experimental, elaborate the advantages of developing the virtual experiment.2. Analyse the necessity and feasibility of developing the computer virtual communication experiment system.3. Present the basic architecture and design patterns of virtual communication experiment system,choose vb.net as the development tool, use the structured and object-oriented method to develop the system, each subsystem function and structure were made by detailed design.4. Achieve the main content and basic functions of virtual communication experiment system.Focuses on the development process of each subsystem in the implementation methods and key technologies.5. Concludes with a discussion of the inadequacies of the system and put forward further ideas and applications outlook.
